Plumbing in the Home/BACK FLOW INTO KITCHEN SINK

I had the same problem in my condo unit. I installed a ball valve right before the P-trap on my sink so that when I go away I can turn it closed and not worry about the water coming back up the drain. Ideally I am still looking for some sort of a check valve that can be used on sink drains so that I don't always have to remember to shut off the ball valve when I leave. Another thing to remember with a ball valve setup like this, is that if your sink faucet drips at all and you are gone a long time the drips could fill up your sink and cause a mess that way.

Sounds exactly what I need to do in my unit. What do these ball valves look like, and where do find them.
